In the last post I showed how to install Enterprise Library. Now let's see what the installation results are.

The installation folder (Default = C:\Program Files\Microsoft Enterprise Library 4.0 - May 2008) contains the following folders:

• Bin - contains the binaries you can use in your application. This folder also contains the configuration editor EntLibConfig.exe, which you can use to create and edit configuration files for Enterprise Library.
• Docs - contains the files for Visual Studio help.
• Src - contains the installer file for the Enterprise Library source files.
• Visual Studio Integration - contains binaries that make the configuration editor available in Visual Studio.

If you want to start building application using EntLib, you can add the approriate files from the bin folder to your application.

Let's see what is in the EntLib source. Double-click the msi, click next to install the source for both the application blocks as well as the quickstarts. This results in:

• bin - contains the same as the bin folder above
• Blocks - contains a solution that houses all 42 Enterprise Library projects, see image below. There is also a second solution that additionally contains unit test projects and the actual unit tests to verify correct working of Enterprise Library as you change it. This is a great value that allows you to feel comfortable editing this pile of code while being able to prove you have not broken anything.
• Lib - contains object builder and unity binaries that you can use in your application independent of EntLib.
• Quick Starts - contains sample code in both C# and VB.NET that you can use to see available functionality of EntLib and how to use it in your own applications.
• Scripts - contains batch files to amongst others compile EntLib from the source, register assemblies and to install Northwind database for the quick starts.
